A Beyeler RH 100 press brake loses its control parameters whenever power is removed. The reported control name is “CYBELEC CNC 30 EURO,” but available evidence disputes that designation: the control may instead be a DNC 30, while CNC 3000 is identified as a separate model. Resolve the model identity before searching for a memory-retention battery or ordering parts.
Separate the Symptom From the Suspected Cause
Parameter loss after every shutdown confirms a memory-retention problem, but it does not prove that a replaceable battery is installed or that battery failure is the root cause. The battery location, construction, voltage, and part number are not established by the available evidence. Incomplete machine schematics make a visual search alone unreliable.
| Item | Evidence status | Engineering decision |
|---|---|---|
| Machine | Beyeler RH 100 confirmed | Use the machine identification when requesting documentation. |
| Reported control | CYBELEC CNC 30 EURO | Treat as unverified until checked against the hardware label. |
| Alternative designation | DNC 30 suggested | Check whether “CNC 30” is a transcription or reading error. |
| Other named model | CNC 3000 | Do not confuse CNC 3000 documentation or parts with DNC 30 hardware. |
| Battery location and specification | Unknown | Do not select or replace a battery without model-specific documentation. |
Verify the Control Identity
Inspect the control enclosure, operator panel, and circuit-board labels for the exact model designation. Record the complete text as printed, including whether it reads DNC 30, CNC 3000, or another designation. Photograph connector locations and board markings before disconnecting hardware; the incomplete schematics may not support reconstruction afterward.
Use a Controlled Troubleshooting Procedure
- Keep the machine powered only under the site’s approved electrical and machine-safety procedures, then record the parameters before another shutdown if the control still exposes them.
- Verify the control model directly from its labels rather than relying on the reported “CNC 30 EURO” name.
- Request the correct memory-retention and board documentation through a Cybelec service channel, supplying the Beyeler RH 100 identity, control label, board markings, and parameter-loss symptom.
- Use the model-specific documentation to determine whether retention depends on a battery and, if so, its board location and replacement requirements.
- After the documented repair, restore the recorded parameters and perform a controlled power-off and restart test.
Verify Parameter Retention
The repair is verified only when the restored parameters remain present after a controlled shutdown and restart. If they disappear again, do not assume another battery is required; return to the confirmed model documentation and investigate the documented retention circuit or memory hardware through the appropriate service channel.
FAQ
Where is the battery in a Cybelec CNC 30 EURO control?
The evidence does not establish a battery location or confirm that “CNC 30 EURO” is a valid model designation. Read the hardware label first and obtain documentation for the identified control.
Is a Cybelec CNC 30 actually a DNC 30?
The reported designation is disputed, and DNC 30 is the suggested correction; CNC 3000 is also identified as a different model. Verify the printed control and board labels before selecting documentation or parts.
How do I confirm the Beyeler RH 100 parameter-loss repair?
Record and restore the parameters, perform a controlled shutdown, restart the machine, and confirm that the same parameters remain available. Continued loss means the retention fault has not been resolved.
